Bosch Copper with Nickel Spark Plugs offer improved performance and reliability over standard copper spark plugs. A heavy-duty yttrium enhanced nickel-copper center electrode ensures exemplary reliability and durability for up to 50% longer performance life vs. Standard copper plugs. The proprietary copper core offers a broader heat range, reducing the risk of pre-ignition and deposit build-up to help maintain OE-level performance and economy over time. The precision engineered, angled ribbed insulator design keeps flash-over causing oil, grime, and debris out of the spark plug wire or coil on plug boot, ensuring electrical energy goes into the spark plug - not around it preventing potentially damaging misfire. A metal-glass fused resistor maximizes interference suppression, protecting sensitive onboard electrical components like engine management modules, sensors, sound systems, and other sensitive electronics from undesirable RF energy. Premium nickel-plated rolled threads provide maximum resistance to corrosion - ensuring the spark plug removes easily from the cylinder head without galling - and does not require anti-seize during installation - saving time.
